In this paper a comparative study of MIMO systems performance is presented by investigating a bodyworn antenna system and a handheld terminal system, taking into account the presence of the user's body. The effects of the correlation coefficient, the radiation efficiency and the number of receiving antennas on MIMO channel capacity are addressed. Extensive study is carried out to examine how these three parameters influence the performance of the two MIMO systems under study, in order to be able to select between a handheld multiple antennas terminal and a bodyworn multiple antennas system for a MIMO system implementation.
